Question

why is cycas called a gymnosperm​

Answer 1

Explanation:

The cycads are considered to be gymnosperms, because they bear their seeds naked on modified leaves called sporophylls. Cycads are sometimes referred to as”living fossils“because they are very similar to extinct species that were much more abundant several hundreds of million years ago.

Hope it well help you

Answer 2

Answer:

Gymnosperms are plants which produce “naked” seeds - unlike angiosperms where the seed are enclosed in an ovule. All conifers are gymnosperms, as are cycads, the gingko, weltwitschia, gnetum and ephedra. Cycas is one genus of cycad.

It is not that Cycas is called gymnosperm - it is that Cycas is a genus within the much wider group of plants called gymnosperms
